Recently, ambient backscatter communication has been introduced as a cutting-edge
technology which enables smart devices to communicate by utilizing ambient radio …

Internet of Things (IoT) is a key technology for enabling ubiquitous applications that
interconnect with cyber-physical systems in various environments. However, its large scale …

We present BackFi, a novel communication system that enables high throughput, long range
communication between very low power backscatter devices and WiFi APs using ambient …

We present HitchHike, a low power backscatter system that can be deployed entirely using
commodity WiFi infrastructure. With HitchHike, a low power tag reflects existing 802.11 b …

In this paper, we look at making backscatter practical for ultra-low power on-body sensors by
leveraging radios on existing smartphones and wearables (eg WiFi and Bluetooth). The …

We introduce the design and implementation of FreeRider, the first system that enables
backscatter communication with multiple commodity radios, such as 802.11 g/n WiFi …

We present the first battery-free cellphone design that consumes only a few micro-watts of
power. Our design can sense speech, actuate the earphones, and switch between uplink …

There is the long-standing assumption that radio communication in the range of hundreds of
meters needs to consume mWs of power at the transmitting device. In this paper, we …

WiFi backscattering can enable direct connectivity of IoT devices with commodity WiFi
hardware at low power. However, most existing work in this area has overlooked the …

Backscatter provides dual-benefits of energy harvesting and low-power communication,
making it attractive to a broad class of wireless sensors. But the design of a protocol that …
